SerialNo. 425,097.

My invention relates to that class of seats, intended to be adjustable so as to bring the eyes of the engineer to the desired level, re-

gardless of his stature; V

My invention has for itsiprincipal object, to provide a seat which is adjustable as'to v height, but which is a unitary structure fastened securely only to the floorof the cab, and

' not in any way secured to the back or side of the cab, thus getting away from the vi- V bration of the back and sides ofthe cab, which is much greater than the vibration of its rather sturdy floor. I 3

Another object of my invention is, to have the seat so'constructed that the seat cushion can befolded up outof the way, thus permit ting the engineman to stand up while switch ing, etc., free from any hindrance due to his seat.

A further object of my invention is, to have i all castings interchangeable, i. e. no rights and lefts, thus greatly reducing the labor cost in assembling.

Still another objectof my invention is, to

do away entirely with ratchets, pawls or sprin s in the adjustment of the seat to various levels, the adjustment being held securely by the weight of the seat, to which is added the weight of the person seated therein.

A concrete device embodying my invention Fig. lis a front'view, partly in section,

showing my improved seat I Fig. 2 is a side view, also partly in sectlon;

Fig. '3 is a side view, showing the seat 7 raised to change its elevation;

.Fig. 4 is 'a top or plan view, partlyin sec- 3 tion;

Fig. '5' is a front view of the frame; and Fig. 6 is a fragmentaryfdetail view of a modified form of construction.

- A shown in the drawings, the Seat frame Similar reference numerals refer to similar parts throughout the entire description.

I comprises uprights 1 and 2, which are connected by a top or cross bar 3. To this are -secured the supports4 and 5 forthe back cushion 6. In thefront edges of the uprights land 2 are formed racks 7 each consisting of a plurality of notches which are fitted to receive ribs 8, cast between guides 9 and 10 formed on a supporting element 11 which supports the entire sliding unit.

There are two of these supports 11, each of which has a 'rearwardly extending arm 12 which terminates in a rectangular guide 13 which encircles one of the uprights'l and 2 respectively. The rear wall 15 of the guide 13 slants outwardly to enable the seat 16 to be tipped, as is more clearly seen in Fig. 3. ,The seat cushion is carried on a frame 17 of angle iron, the sidesr of which are supported by brackets 18 and 19. These brackets 18 and 19 are secured, by; means of bolts 20, to the supports 11. This construction permits the seat 16 to be tipped up, as shown in Fig. 2, to enable the engineman to stand without in any manner changing the position of the sup ort 11 with relation to its height from the oor 21 of the cab.

The back cushion 6 is supported by steel framework, comprising two members 23 and 24, which are clearly seen in Figs. 1 and 5 (and in side elevation, in Figs. 2 and 3), thus proclucing a double spring action which makes for a restfulback, a single straight upright being too rigid to be at all comfortable.

v The uprights 1 and 2 are preferably supported by detachable feet25 and 26, which are and 26 detachable, it becomes very convenient to slip the uprights 1 and 2 through the guides 13, as well'as making it easier to attach the feet 25 and 26 to the floor 21 than Would be the caseif they were underneath the supports 11 and the frame 17.

From the foregoing description, it will be clearly seen that in order to raise or lower the seat 16, it is only necessary to tip supports 11 up, as seen in Fig. 3, the slanting of the rear walls 15 of the guides 13 permitting this movement. This lifts the ribs 8 out of the notches in the racks 7 in which they wereresting, and. the seat 16can be freely moved either upwardly: or downwardly. Itis important that guidesSand 10 be made of a length suflicient so that, when constructed to give a wide fiat bearing on the floor 21 of the cab. By making the feet 25 I the supports, 1 1 are pulled out to the fullest extent possible,'these guides 9 andlOwill stillperform their ofiice of keepingthe sup the edges of the uprights *1 and 2.

ports 11 lined up with'the racks 7; In some cases it. may be found desirable to cast racks 7 separately, instead of forming groovesin This manner of constructionis shown in Fig. 6,;in which the rack 27 is a separate casting,vbolted or rivetedftov theuprightil As 1 shown,'it' is secured by a rivet 28, whi'chfeX- tends through a lug'29, cast orY-formedim -tegral with the rack casting'Q'ZY'This construction permits the use of very much lighter uprights, and hence effects a saving in the,

cost "of manufacture without" sacrifice-of strength. 1 r V e p y 1 Having described "invention, what regard as new,fand*desire to secure by Letters Patent of the United States, "is: 1.
